Overview
The Littelfuse SJ6012D1RP is a Silicon Controlled Rectifier (SCR) from the SRR60 series, designed for phase control and general switching applications. It features a DPAK-2 (TO-252-2) surface-mount package with glass-passivated junctions. The device supports a repetitive peak off-state voltage of 600 V and an RMS on-state current of 12 A. Key electrical parameters include a maximum non-repetitive surge current of 120 A, a holding current of 6 mA, and a gate trigger current of 6 mA at less than 1.5 V potential. It operates within a temperature range of -40°C to +110°C.
Feature Summary
- Sensitive gate design allows triggering with microampere currents from sense coils or proximity switches
- Standard phase control configuration triggered by few milliamperes at low potential
- Glass-passivated junctions provide robust protection against environmental stress
Applications
- Phase control circuits
- Heating control systems
- Motor control applications
- Capacitive discharge ignitions
Procurement Notes
Verify the exact part number against official Littelfuse documentation, as the specific model SJ6012D1RP may be a variant or typo of the documented SRR6012D1RP. Confirm RoHS compliance and REACH SVHC status through the manufacturer's latest datasheet before integration. Ensure the ordering suffix matches the required packaging format, such as reel quantities, to align with production requirements.
Selection Notes
Select this component for applications requiring reliable unidirectional switching in power electronics. The TO-252-2 package facilitates automated surface-mount assembly. Consider the 600 V rating for medium-voltage AC line applications. Verify that the gate drive circuit can supply the necessary trigger current, which varies between sensitive and standard gate types within the series.
Part Context
This SCR belongs to the Teccor brand thyristor family manufactured by Littelfuse. The SRR60 series is engineered for high reliability in industrial and consumer power control environments. These devices are commonly used where compact size and efficient thermal management are critical for system performance.
Replacement Considerations
Direct substitutes may include other 12 A, 600 V SCRs in TO-252 packages from Littelfuse or competitors. Verify pinout compatibility and thermal characteristics. Cross-reference with the SRR6012xx series for similar electrical ratings if exact matching is unavailable.
